2 Claims.

The present invention relates to an improved type of egg carton and hasas a particular object the provision of a cushion style carton in whichan effective protection may be afforded for fragile articles carried inthe carton without the suspension of the bottom of the bottom member inupwardly raised position by engagement thereof with the longitudinalpartition or cross walls.

An additional object of the invention is to provide an egg carton of thetype described in which a cushion bottom is provided by sloping thebottom sections downwardly and inwardly from the front and rear walls toprovide the carton with a bottom section of V-shape, the outer wallsbeing balanced by extending down to the lower portion of the carton andbeing joined by a flat bottom section.

Still another object of the invention is the construction of an easilyerected container having a separate longitudinal partition orcenterboard and a double bottom, the inner bottom being inwardly anddownwardly sloping.

These and other objects will be observed upon a consideration of thefollowing specification and 25 by reference to the accompanying drawing,in

which Fig. 1 is a top view of a carton constructed in accordance withthe invention, the cover of the carton being shown in open position;

Fig. 2 is an end view of the carton shown in Fig. 1, with the coverclosed;

Fig. 3 shows the separate longitudinal partition used inthe carton ofFigs. 1 and 2; and* Fig. 4 is a view of the blank from which the 35carton shown in Figs. l and 2 is constructed.

As shown in. Figs. l to 3, the carton is constructed by cutting, scoringand folding a single blank of paperboard to form a cover locking strip I0 having hook portions I I, a cover I 2, a rear wall I3, an outer bottomsection I4, a front wall I5, cross partitions I6 hinged to the frontWall by means of hinge members I'I, an inner rear wall I8 hinged to theopposite side of the cross partitions by means. of the hinge members I9,a rear inner bottom section 2D, a front inner bottom section 2l and amarginal strip 22 attached to the latter. The inner front bottom section2I is cut away to provide a series of tabs 23 which remain on the strip22 when the carton is erected, as will be seen in Fig. 2.

In the construction of the carton the blank is cut and scored and inassembly the inner rear wall I8 is folded over and, glued to the outerrear wa-ll I3, the bottom sections being folded inwardly of the cartonwith the strip 22 lying loosely adjacent the front wall I5. Thisrelation will be seen from an observation of Fig. 2. In collapsedcondition the cross partitions are in the horizontal position shown inFig. 3. The ends of the cross partitions are cut away so that they donot 5 extend downwardly as far as the inner bottom wall. Adjacent oneend of the carton the cross partitions preferably are of the split celltype in which the material between adjacent longitudinally spaced hingesis used to provide two 10i adjacent oppositely directed 'crosspartitions 2li, these partitions being of less length than the remainderof the partitions, as will be seen in Fig. 2.

To set up the carton the longitudinal partition 15 shown in Fig. 3 ispressed into engagement with the horizontally extending crosspartitions, thereby rotating the cross partitions into verticalposition. The hooks 26 on the longitudinal partition are engaged beneaththe cross partitions to 20 maintain the longitudinal partition inengagement therewith.

The carton may be collapsed along the score lines between the hingeportions l1 and the front wall. In this case the bottom sections and the25 strip 22 lie in a plane along the outer bottom section and the frontwall. ,The strip 22 will project along the front wall to a pointadjacent the upper portion of the latter, due to the greater length ofthe inner bottom sections as compared 30 with the outer bottom sections.The carton also may be collapsed along the score lines between the strip22 and the front inner bottom member 2l also may be collapsed along thelower front wall and the score line between the inner rear wall i8 andthe hinges I9. In this case the strip 22 is folded over adjacent thefront section 2|. and the tabs 23 rest adjacent the outer bottomsection.

It will be noted that the continuous inner bottom wall a-iords a cushionfor eggs placed in the carton and extends downwardly and inwardly.Cushion bottom cartons having a continuous bottom wall heretofore haveextended upwardly and inwardly in substantially inverted V-shape. Theupwardly raised central portion of these previous cushion cartons aresuspended by engagement with cross partitions or with the longitudinalpartion. By sloping the inner bottom section downwardly and inwardly nosuch suspension means are necessary, it being satisfactory simply toprovide the tabs 23 for bracing the loose outer end of the inner bottomsection. The longitudinal partition extends downwardly the completeheight of the carton and upwardly to the top of the carton, therebya-iording substantial bracing effect which helps materially to preventbreakage of eggs.

An advantage of this type of carton is that it may be erected withextreme rapidity by hand. In erection a collapsed carton is grasped inone hand of the operator and the walls are squared. Thereafter, thelongitudinal partition is thrust downwardly into engagement with thecross partitions, this latter operation being particularly easy in Viewof the short cross partitions and. the downwardly and inwardly extendingshape of the inner bottom wall.

It will be noted that the outer bottom wall is flat and provides addedprotection for the eggs. The cartons may be stacked without collapsingthe carton or endangering the bottom.

It will be recognized that many changes may be made in the constructiondescribed specifically herein without departing from the scope of theinvention as dened in the appended Claims.

I claim:

l. A carton of the type described, comprising a blank cut, scored andfolded to form a rear wall, a continuous flat bottom, a front wall,cross partitions hinged to said front wall, an inner rear wall hinged tosaid cross partitions, an inner rear bottom section extending downwardlyand inwardly adjacent the center of the carton, an inner front bottomsection integral with said inner rear bottom section and extendingoutwardly and upwardly adjacent the front wall, a marginal stripconnected to said inner front bottom section, and tabs struck from thematerial of said inner bottom section extending downwardly from saidmarginal strip.

2. A carton of the type described, comprising a blank cut, scored andfolded to form a rear wall, a continuous at bottom, a front wall, crosspartitions hinged to said front wall, an inner rear wall hinged to saidcross partitions, an inner rear bottom section extending downwardly andinwardly adjacent the center of the carton, an inner front bottomsection integral with said inner rea-r bottom section and extendingoutwardly and upwardly adjacent the front wall, and a marginal stripconnected to said inner front bottom section.
